1. A system for delivering a pressurized ablation liquid to a cavity of a patient comprising:
a) an elongated member having a fluid channel for passage of the pressurized ablation liquid into the cavity of the patient and into direct contact with the endometrium, the fluid channel having an opening open to the uterine cavity to provide for passage of the pressurized ablation liquid, the pressurized liquid injected directly into the uterine cavity at a controlled pressure; and
b) an infusion line in communication with the elongated member for passage of a fluid different than the ablation liquid through the elongated member into the cavity to assess leakage to determine integrity of the cavity prior to passage of the pressurized liquid into the cavity and
c) wherein the ablation liquid passes through the fluid channel and through the opening, wherein the ablation liquid at a source entering the elongated member is in a same state as the ablation liquid exiting the opening.
